Abstract
A masking tape is provided that is suitable for insertion under many moldings and gaskets which not only masks the molding or gasket but also facilitates refinishing under at least a portion of the molding or gasket. The masking tape is constructed to include a longitudinal non-adhesive portion and a longitudinal adhesive portion, wherein the non-adhesive portion is stiffer than the adhesive portion and is sufficiently stiff to facilitate easy insertion of the non-adhesive portion beneath at least a portion of the molding or gasket to be masked while the adhesive portion is sufficiently flexible to permit the wrapping thereof around the molding or gasket. The stiffened portion advantageously provides a dual purpose of facilitating the easy insertion of the non-adhesive portion beneath the molding or gasket and creating a lever action during application between the molding or gasket and the wall or panel to which the molding or gasket is mounted. This lever action creates a force which tends to separate or lift an edge of the molding or gasket from the wall or panel to open the wall or panel under the molding or gasket for refinishing. The masking tape is especially applicable for masking flexible gaskets that include a leg portion that overlies an adjacent panel that is to be refinished.
Description
Technical field
The present invention relates to a kind of in the operating process of refinishers such as pre-treatment, sand milling, paint for covering the cover band of not refitted zone as using along a kind of filler rod of panel setting or liner.This panel can be used as car body, steamer, aircraft, house, trailer or buildings, or the part of the wall of other structure.The invention particularly relates to a kind of like this band structure, it is used to cover this class filler rod and liner etc., can protect crested zone effectively and allow directly adjacent with it and preferably at least in part the zone under the crested thing carry out surface dressing.Technical background of the present invention
Covering band uses in the paint operation of various refinishers usually.This generic operation comprise paint or seal a surface and for paint sand milling or pre-treatment should the surface.Used this term of paint means and comprises with spraying or with other brushing method spreading such as painting brush, cylinder paint and other similar processing in whole specification sheets, comprises any material is applied on the surface that a part need be handled and covers the surface that another part need not be handled.This term meaning of described refinisher comprises the arbitrary surface of paint, sand milling or pre-treatment, and wherein part surface need be painted.In general, this is meant a surface of before having been painted.
The trimming operation is carried out on the wall of being everlasting, car body and similar position, and it comprises the filler rod and the liner that must be covered before painting.Preferably can cover this class filler rod or liner effectively, but can guarantee to its edge and as if possible preferably in addition the edge under filler rod or liner carry out complete trimming.Be to cover to bring with traditional papery this class filler rod or liner are covered as everyone knows.Yet, singly be that the edge along filler rod or liner covers the finishing that at all can not improve under filler rod or the liner.The effective area of surface preparation and paint only extends on the edge of masking material.Such effective area be impossible with scheme as an alternative, if promptly before paint, filler rod or liner taken away in this case obtainable effective area comparable.In addition, paint trends towards along the edge that covers band, perhaps at filler rod itself or assemble onboard, and cover be with removed after, the paint ridge often stays, this subsequently paint ridge splits or fragmentation especially easily.
So preferably at least in preparation below the edge part of the filler rod that covered or liner with obtain some paint effective area at least.Ratify to having disclosed a kind of adhesive tape sticking method in the 3rd, 935, No. 758 United States Patent (USP)s of Burqin people such as (Polzin) and a kind ofly being used to paste this instrument that covers band on February 3rd, 1976.By this announcement, be to paste with specialist tools a kind ofly typically to cover band, so that be wound at least in part below the edge and car body side filler rod of the side filler rod on the car body.Even the problem of following this method to produce is to use a kind of specialist tools, also be difficult to sealing tape stick on the filler rod that is connected with this body or similarity piece any part below.If the spacing between filler rod and the body panels (crack) is minimum, this problem just becomes more outstanding so.
For liner, especially, when they when body panels is provided with, it is suggested and on the end face of face under the liner part and body panels, inject an elongate articles in order to improve cushioning material, with keep itself and the separating of body panels, and in the scope of the topped at least body panels part of liner.This elongate articles is injected under liner edge, so that a part that is exposed to the body panels under the liner is at least painted with sufficient length.
Many these class inserts have been developed.It should be noted that most that rope, cable, line and other tape are all applicable at present, they be made into can inject on this soft cushioning covered portion and the body panels that is laid on.This this rope, cable, line and tape are lifted away from body panels to allow to carry out the surface dressing of part below liner with the covered portion of cushioning material; Yet liner itself must be covered in addition.In addition, be to paint to gather to stay the paint ridge on its edge and after device is taken away in company with the problem that this device produced.Verified this paint ridge is easy to split and is broken, this split and fragmentation can extend out under liner.
A kind of by the New Jersey, an example of the plastics cable that the Tru in Garfield city-Mask Products Co., Ltd produces is suitable for, and it is called as Follex
System, this plastics cable is inserted into below liner edge and makes it be lifted away from body panels to be used for refinisher.Disclosed the example of the similar nettle of other, cotton rope or enameled wire in No. 47-18930, the disclosed Japanese patent application of announcing in September, 1972.
In addition, the product that covers of another kind of pattern has also been developed in covering of relevant soft liner, and it can move and cover liner in a single operation.In disclosed, disclosed a kind of like this product that covers in the PCT of the EP/92/01021 of the Bick application.The Bick shading unit is made up of a stripping in described, and this stripping longitudinally is divided into two shanks so that ribbon construction becomes a long claw-like or hook formation.A described hook-type shank of structure is inadherent, and it is configured to be hooked on the part of liner or liner, is used for band is bonded to the object that is covered and another leg scribbles binding agent, for example on the window.This product depends on the structural integrity of device and in order to operate, and two legs keep its at angle position toward each other.In other words, the profile that covers product must keep the certain rigidity of itself so that the effect of its hook can be provided.
Another kind of specialized designs becomes to be used to cover the product that covers with the adjacent areas of being painted, and is to be used for along the topped fresh paint of shield wire or with fresh paint and the mixed such product of old paint.Say that typically a kind of like this product that covers is made up of an adhesive tape with an inadherent longitudinal edge portions.With the most close non-adhesive segment in the zone of refinisher for the treatment of this band that covers is bonded in abutting connection with treating on the zone of refinisher then.When paint when topped band sprays, non-adhesive segment just makes fresh paint mix along the surperficial topped old paint below non-adhesive segment or with old paint.Ratify to give in July 27 nineteen eighty-two and disclosed this class in the 4th, 576, No. 674 the United States Patent (USP) of Li Tate and cover band and divider to the 4th, 576, No. 674 of Stephens and approval on March 18th, 1986.As long as just can obtain described NAG longitudinal edge to make it becoming non-adhesive segment by in the process operation process, in the edge section or only one tape material being applied on the binding agent along the edge of adhesive tape without the binding agent spreading.Back one mode is to cover on the adherent side of band and just can finish as long as fold into a tradition by the longitudinal edge itself with adhesive tape.General introduction of the present invention
The present invention by provide a kind of be suitable for injecting under many filler rods and the liner covering band overcome with prior art cover the shortcoming and defect that is associated of band, band is covered in described the present invention can not only cover filler rod or liner, but also helps at least under the part of filler rod or liner face surface dressing in addition.
According to the present invention, one covers band is made into and includes a vertical non-adhesive segment and a vertical adhesive segment, wherein, described non-adhesive segment is harder than the bonding part, and be rigid enough to help with non-adhesive segment easily inject the filler rod that covers to waiting a little while,please or liner a part below, be wound on filler rod or the liner to allow it and adhesive segment has enough flexibilities.
Described hard component has advantageously provided double utility: the first help easily with non-adhesive segment inject filler rod or liner below, it two is a kind of leverages of generation in the application that filler rod or liner is installed between filler rod or liner and wall or the plate.This leverage produces a power, and this power trends towards an edge of filler rod or liner being raised or liner edge being separated with wall or plate, thereby to the wall of face under filler rod or liner or plate surface dressing in addition.
According to the present invention, the described band that covers especially can be applicable to cover soft liner in addition, and this soft liner includes a topped need shank of the adjoining plate of surface dressing in addition.Described NAG hard component can inject along the length of the liner of crested the liner shank below.After this, the softer adhesive segment coiling liner that covers band and be bonded to liner and next adjacent bottom on (if having this spline structure).In adhesion step, use opposite edge that the operator's traction cover band covers band so that the leverage that produces rigid tape facing to body panels and liner shank.The liner shank is pushed up from body panels and is held it in by adhesive segment on the position of this raising then like this.Rigid tape cover band in a lateral direction must be firmly to not only being enough to produce leverage but also keeping undetermined for some time covering arranging with basic collinear in a lateral direction of band.In addition, in this undetermined for some time process, cover band and should be able to bear certain variation under the envrionment conditions.To the situation of the surface dressing of a body panels time, plate and cover that band often will be subjected to abrasive, chemical solvents and the effect of the elevated temperature of 120 ° of-180 (49-82 ℃) scopes of painting for the oven dry plate.Cover band and must be able to stand the above-mentioned envrionment conditions of special applications.The invention still further relates in the refinisher operating process and use the method for covering band to raise with the mode of fixed-bearing shank.Brief description of drawings

With reference to these accompanying drawings, every identical label is all represented same part in each figure, at first referring to Fig. 1 and 2, and a band that covers with roll form shown in the figure.In general, cover and be with 10 to be longitudinally to be divided into an adhesive segment 12 and a non-adhesive segment 14.Adhesive segment 12 is more satisfactory, and to be most of width of comprising occupied frequency hand 10 be fixed on the crested object and can stop the additional offset that is produced by special application to keep this fixing equably to guarantee to have enough binding agents will cover with 10, and this can be from following to understanding some special explanation of using more fully.The width of non-adhesive segment 14 also mainly is to depend on the special application of covering with 10.More specifically say, the width of non-adhesive segment 14 depends on that non-adhesive segment 14 is inserted into degree under filler rod and the liner etc. and whether it affacts on filler rod and the liner etc., and this effect also can be understood from the explanation of following special application more fully.In a preferred embodiment of the present invention, to bringing of the width of one 2 inches (5.08 centimetres), non-adhesive segment has the width of measuring 0.375 inch (0.95 centimetre) obtaining from an edge.
Of the present invention cover with 10 basic structure include on the part of major surfaces that a back sheet 16, is located at back sheet 16 at least tack coat 18 and along a rigid device of non-adhesive segment 14.According to the preferred embodiment of covering with 10, non-adhesive segment 14 is to form by the edge section with rigid tape 20 topped tack coats 16, and described rigid tape 20 also comprises above-mentioned rigid device.A kind of so rigid tape 20 can have many different shape and size, but preferably uniformly and have a rectangular cross section shown in Fig. 2.Be understood that 14 of non-adhesive segment otherwise the spreading binding agent is just obtainable thereon.Under the sort of situation, rigid device can obtain by a hardened layer is applied on the non-adhesive segment, or the tape of hard material can be fixed on the non-adhesive segment as the method with thermal welding with method for distinguishing.In addition alternatively, the backing of binding agent spreading can be folded in or be wound on the rigid tape to form non-adhesive segment.Also can plant alternative as other, the back lining materials folded edge can comprise rigid and form non-adhesive segment.
Described covering with 10 can also comprise a topped adhesive segment 12, the particularly lining 22 of the expose portion of tack coat 18, covers the surface of protection tack coat 18 when having roll-good form with 10 with box lunch.If lining is not to provide with roll-good form, then near the edge of rigid tape 20, have at least a part of tack coat 18 surfaces to be exposed in the air and partly oxidation.
It may be noted that also tack coat 18 is not the whole main surface that must toppedly cover with 10 adhesive segment 12.On the major surfaces of the back sheet 16 in adhesive segment 12 any one can be by well-regulated or irregular pattern or along with hard tape 20 longitudinal wires adjacent or that be spaced from the zone of binder free being set.In addition, quantity, pattern and the pattern of the width of adhesive segment 12 and tack coat 18 also depend on special application.
A kind of concrete application of covering with 10 is to shelter the elastic packing material that needs the plate of trimming to adjoin with the surface.The example of a kind of pattern of this structure as shown in Figure 3.Shown in the figure is to be used in vehicle body, aircraft, hull, house, trailer, a kind of typical structure on the buildings, these use occasion windows or windsheild 24 by a soft elastic insert 26 around with the window sealing-in on car body board 28.Liner 26 comprises the elastic leg 30 on the part of a topped body panels 28 of the length direction along window 24.
When trimming like this during a kind of body 28 surperficial, not only require pre-treatment should the surface and with paint spraying to the expose portion of car body panel, and below the shank 30 of liner 26, also to partly do so at least so that obtain being similar to the more specialized trimming of original factory paint.As partly describing in detail in this application background technology, be as everyone knows as far as possible down imbed a rope or similar elongated part under the shank 30 and the end face of car body panel 28 on.A kind of like this element can keep the edge of shank 30 to leave car body panel 28 effectively in case paint spraying below the part of liner shank 30.Yet in order to prevent liner 26 by paint institute spreading, it is own just must to use an isolation to cover with topped liner 26.Along with using the problem that this class component produced is that paint trends towards assembling along element, and this can stay the paint ridge after taking off element.Confirmed that this paint ridge splits easily and fragmentation.
The present invention is by raising liner shank 30 effectively and keeping its method of covering liner 26 own (as shown in Figure 4) with separating of car body panel 28 simultaneously to overcome above-mentioned these shortcomings.For reaching this purpose, will cover with 10 stiffened edge 34 and imbed under the edge 20 of liner leg 30 and preferably accomplish as far as possible down to imbed.In addition, covering with 10 hard-edge 34 is to imbed under liner leg 30 along the length of the adjacent whole liner 26 in the car body panel zone of being rebuild with the need surface.Because to cover with 10 is soft, covers band and can accompany or follow most of crooked on the liner 26.If crooked serious, the transverse cutting road that then may also need to provide part partly by rigid non-adhesive segment 14 in cover with 10 or preferably transverse cutting pass through adhesive segment 12 in the knee.Under any circumstance, though only need the part of hard-edge 34 and hard tape 20 is imbedded, preferably whole hard tape 20 imbeds under liner shank 30.
Cover imbedded the next desired length of liner leg 30 with 10 non-adhesive segment 14 after, next step is to be fixed on liner 26 and the adjacent window 24 covering with 10 adhesive segment 12.Simultaneously, liner shank 30 is raised and keep its with car body panel 28 to separate so that carry out surface dressing at least in part below liner leg 30 also be a function of covering band structure of the present invention.In addition, do like this and can the formation of any paint ridge to be minimized after covering band be one object of the present invention taking away.
In order to improve liner leg 30, use the operator of covering to spur the opposite edge 36 of covering with 10 with 10, then adhesive segment 12 is pasted on liner 26 and the window 24.Raise effect in order to produce this, importantly make non-binding part 14 become enough hard so that hard-edge 34 acts on the limit 32 to raise liner leg 30 on the car body panel 28 by facing toward the leverage mode by hard tape 20.According to the embodiment shown in Fig. 1 and 2, it is the subassembly of the edge section of hard tape 20 and back sheet 16, and this subassembly must be rigid enough to the integrity that makes hard tape 20 can keep its structure in raising the process of operation.Be that hard tape 20 is kept the rectilinearity (please see Figure 4) as seeing basically on the transverse section, though it can slight curvature but still keeps its function.
Have again, non-rigid part, adhesive segment 12 must be fully soft so that around liner edge 32 and cover on the liner 26 and arrive on the window 24.The pliability of the hardness of non-adhesive segment 14 and adhesive segment 12 depends on the flexibility of the material that constitutes liner 26.The occurrence of hardness that is suitable for use in certain material of the hard tape 20 on the conventional cushion material is listed in following table 1.Thisly just contain the hardening region of non-adhesive segment 14 and the particular combinations of soft enough adhesive segment 12 just provides the leverage that makes liner leg 30 raise and keep itself and car body panel 28 to leave.The structure of covering band be the mode with a kind of hook spare work and in fact need not cover with on form and the structure of utilization rigid hooks.
It also is an advantage of the present invention that rigid limit 34 is minimized the formation of paint ridge.As shown in Figure 4, because non-binding part 14 is assembled towards the direction and the car body panel 28 of hard-edge 34, therefore will paint the formation of ridge and minimize.By comparison, rope demonstrate one vertical even a dispersive surface is arranged, these surfaces form the paint ridge probably.In addition, hard-edge 34 plays a part a wedge shape fillet.Having in covering the belt edge cutting process along the arbitrary irregularity a little of hard-edge 34 formation advantageously to allow some to spray paint below hard-edge 34.Consequently forming one covers or mixed limit.Further plan especially by a procedure of processing to provide rule or irregular shaping limit, for example the limit of segmental or otch (can have the paint road and improve hard-edge 34 below it.As long as keep the hardness of the transversary of non-adhesive segment 14, then many improvement all are fine.
Suitable covering comprise in the belt material as extensible paper, PVC, polypropylene, polyethylene, polyethylene and polyacrylic multipolymer or any other kind of polymer linner, these linings be soft to enough with on the zone that is wound up into crested.Any suitable binding agent all can be used for purpose of the present invention, for example comprises binding agent, the butylbenzene (mixture of the Kraton type binding agent of styrene-butadiene) rubber (SBR) based binder, acrylate (acrylate) binding agent, crosslinkable hot melt or any they of natural rubber based.Best, used binding agent should not transferred on the zone of crested.Under the situation that is used in conventional cushion material such as EPDM, natural rubber binding agent or natural rubber and synthetic rubber binder mixtures are comparatively ideal, and they have a kind of adjustable cross-linking density so that the balance between plasticity-and the property removed to be provided.
The suitable material that is used for hard-edge can be different with desired application.
Possible various application comprise, for example cover base plate or other rigid structural member, and wherein, non-adhesive segment 14 can be imbedded between wall or plate and the base plate, and cover that band can be wound on the base plate and bonding with it.This band that covers can be used to cover inflexible car body side direction filler rod, shield cap, backplate or other part similarly, wherein, the non-adhesive segment 14 of covering band is imbedded between the part that need be painted and the crested part and is wound on the crested part and bonding with it.Material applicatory and hardness require can be different with the spacer thickness between special purposes and part of waiting to be painted and the crested partly.
Reach as mentioned above more generally, the present invention can be used to the object that covers soft or semi-rigid object or flexibly installed, wherein requires to raise object and keeps itself and the in addition plate of surface dressing or separating to allow to carry out at least the surface dressing of part below the crested object of wall of needs.These purposes comprise, for example blanket are raised and by the fixing blanket of the surface dressing region direction that leaves floor, wall or base plate, or liner raised and keep itself and need the separating of car body panel (this has fully given explanation in the above) of surface dressing in addition.Use for these, the non-adhesive segment 14 of covering band must be thinned to is enough to allow it to imbed under the crested object, also enough hardness will be arranged so that the edge of object can be raised and keep its edge and need the separating of zone of refinisher in addition.
According to being used to raise and keeping the present invention of known gasket construction spare to cover purposes with 10, hard tape 20 can be made by having a kind of any material of raising the proper stiffness of liner leg.The suitable material that can be used for hard tape 20 includes paper, plastic-metal etc.Comparatively ideal plastic material comprises, for example polystyrene, polypropylene, polyethylene, polyvinyl chloride, PET-G, polyester, polycarbonate and their mixture or multipolymer, and more satisfactory is the thickness with about 10 mils (254 microns).Used a kind of Teledyne Taibo 150-D type trier (can buy) about the official(acceptance)test method T489 om-66 of paper and cardboard hardness various such materials to be measured the Taibo rigidity value according to TAPPI from New York Amityville trier company.With the gram-centimeter is that the hardness value that unit records is listed in table 1.The value of reporting in the table is represented the mean value of 5 revision test observed values.

* the paper material of mark, the hardness value of its mensuration depends on the paper fiber direction, i.e. the horizontal machine direction of paper relatively.
The various materials of making hardness test above in table 1 were also once done to be applied to raise and the suitability test of the liner shank of the window pad that keeps being made by EPDM.At first be to determine whether material is rigid enough to inject under such liner shank, and secondly be to determine whether material is rigid enough to be provided as the liner shank is raised or to be kept it to separate required leverage with car body panel.
The sample of wrinkle paper tape and two polyester inadequately firmly to can inject tested cushioning material below.The hard tape work of polystyrene of 12 mils (3048 microns) gets fine, and is at least 20 from the Taibo hardness value of can special for this reason purposes accepting that these data can find out that comparatively ideal reinforcement tape should have.In addition, this acceptable hardness limit value also depends on the structure of cushioning material, yet the not high enough stiffened edge of hardness that is used to inject under the harder PVC liner but can be applicable under the softer EPDM liner of reeve well.
In addition, the back sheet material is more soft significantly than the material of hard tape 20.So just allow backing layer 16 can be wound on the liner edge or on other object and can adverse influence not arranged to the function of hard tape.In addition, this unitized construction does not form actually under the situation of a hinge a kind of hinge effect but is provided.Have same hardness if cover the whole width of band, then need a hinge lines to produce leverage.It is also understood that if thickness is done correspondingly to change, then same material both can be used for hard component and also can be used for non-rigid part.The most desirablely be, back sheet material also extensible is significantly measured, so that in use, covering band can be in its stretching, extension in a lateral direction.
Aforesaid being applicable to is covered liner and can be raised and keep the ideal structure that covers band of its liner shank shown in Fig. 1 and 2, it comprise one 2 inches (5.08 centimetres) wide/the thick PVC backing of 4 mils (102 microns), backing has the crosslinked natural rubber binding agent of phenolic aldehyde with 6.3 grains/24 square inch (26 grams/square metre) spreading.Hard tape is the most desirable to be to comprise the PETG copolymerization film that one 3/8 inches (0.95 centimetre) is wide, 15 mils (381 microns) are thick (a kind of glycerol, modified version polyethylene terephthalate).It also is comparatively ideal that the thick barrier liner of 6.4 mils that can sell on a kind of market (162 microns) includes on paper one side that spreading has polypropylene and polyethylene is arranged and scribbling a kind of paper that has silicon LAB on the poly surface at spreading on the opposite side.A kind of like this barrier liner can be bought from the PWA Kunstoff company limited of German Raubling.
Referring now to Fig. 5, will illustrate that below of the present invention covering with 10 is applied to the situation of a body side to filler rod 40.This side direction filler rod is to be fixed on the car body panel 42 with traditional method as shown in the figure.Typically, this mounting block can comprise just like among the figure with the tape of porous plastics bands of 44 expressions.Spacing be on the fixing strip 44 and under filler rod 40 and car body panel between form, fixing strip 44 can be used for injecting the non-adhesive segment 14 of covering with 10.After this, take away liner 22 (as setting), and adhesive segment 12 is reeled and is pasted on the filler rod 40.As in above-mentioned application, hard tape 20 provides two kinds of purposes: the first helps non-binding part 14 is imbedded between filler rod 40 and car body panel 42, and it two is to trend towards the edge of filler rod 40 is lifted away from car body panel 42.Any rise depends on the deformation extent of body strip 40 or stationary installation, for example is the degree that deflection allowed of porous plastics band 40.If the two side areas of filler rod 40 all needs surface dressing in addition, then a tape that similarly covers with 10 will in kind stick between the following spacing of filler rod 40 and car body panel 42.
Can contemplate easily from this explanation it is how can be applied that the present invention is covered with 10 under countless situations, as long as the spacing of imbedding non-adhesive segment 14 is arranged, hard tape 20 just can help non-adhesive segment to be injected this spacing and can trend towards expansion or open this spacing by the leverage of hard tape 20 facing to plate or wall.It must be soft enough to allow to carry out this embedding that yet an in esse spacing or object must be arranged.
Have under definite spacer conditions, but be under the stone situation for the object that is installed in plate or wall, the hardness of non-adhesive segment 14 is not very main just, and in fact, simple vertical non-adhesive segment of a soft back sheet 16 can be enough.
Covering of a dual usefulness shown in Figure 6 is with 100, and it comprises a rigid longitudinally non-rigid longitudinally non-binding part 106 of non-binding part 104 and of adhesive segment 102, longitudinally.One back sheet 108 has and constitutes the whole transverse width cover with 100.Tack coat 110 is the zones that are coated on the major surfaces of back sheet 108 except non-rigid, non-binding part 106.One hard tape 112 is bonded on the back sheet 108 in the rigid non-adhesive segment 104 and is used to provide inadherent part.
Mode as an alternative, tack coat 110 spreadings can be used in the whole surface of back sheet 108, but not adhesive segment 106 can have bonded second a hard tape on it, and it has the thickness different with the first hard tape 112.In this case, in fact part 106 can be a hard component.
For as the same cause in the top previous embodiment, protective lining 114 also preferably has the band of web-like.
This covering with 100 provides a kind of relevant covering with 10 embodiment to carry out the band that covers of above-mentioned all application of realizing.In addition, this covers the scope of application that has in those situations of just having discussed with 100 in the above, has definite spacing in these situations, but the installation of object is too hard for injecting thicker rigid non-adhesive segment 104.Especially, non-adhesive segment 106 can be with in this case.As long as adhesive segment 102 is designed to and can uses as described above, non-adhesive segment 104 or 106 arbitrary parts existence, and when using another part, can not seize the function of covering band yet.In fact, advantageously obsolete non-binding part 104 or 106 can help to take away from the surface of crested covering band after the surface dressing operation is finished.
Clearly can also be to the covering band and make many other improvement of this theme according to the present invention, in addition this theme being covered band, can to have many other purposes this point also be self-evident.
